Assunto: Re: [DUG]: TStrings.Objects
SNIP - Lot's of talk about the qualitative use of storing explicitly
cast data into
TStrings.Object storage areas in preference to recognising pascals
assistance in
strong-typing and support for extensible class instance storage.

From the point of views taken storing non pointer data is exactly
the same:
var
A :TObject;
A is just a pointer - it happens to be a typed pointer that the
compiler knows to treat
differently, but it's still just a pointer into memory.
